I knew he was sick, and i didn't figure he'd last the year, but it still makes me sad that one of my heroes has passed away:

Dr. Robert Moog, known for the synthesizer that beared his name, died at his home in Asheville, North Carolina on Sunday. He was 71. The inventor of the Moog synthesizer — whose variants have been used by everyone from Pink Floyd to Kraftwerk, Duran Duran, the Black Eyed Peas and the Neptunes — was diagnosed with inoperable brain cancer in April and had received radiation therapy and chemotherapy to combat the disease, according to a post on his official Web site.

Born on May 23, 1934 in New York, Moog began tinkering with early versions of electronic instruments as a teenager. After writing an article about them in 1954, he opened a business building and selling theremins, machines in which pitch and volume could be controlled by the wave of a musicians' hand. Moog earned degrees in physics, electrical engineering and engineering physics before staring out on a path that would turn him into an icon for generations of modern musicians.
